A retrospective review of calls to the Poisons Information Helpline of the Western Cape during the first 6 months of the COVID-19 pandemic in South Africa

Background: Since the start of the coronavirus disease 2019 (COVID-19) pandemic, poison centres worldwide have reported an increase in exposures to chemicals used for infection prevention. Increased availability and use could lead to an increase in exposures. Potential effects on a South African Poison Information Helpline were unknown, therefore a study was performed to describe changes in call volume and profile of poison exposures. Methods: A retrospective analysis was conducted on an observational database of telephone enquiries. All human-related poisoning exposure call data collected from 01 March to 31 August during 2018, 2019 and 2020 were extracted and analyzed. Summary statistics were used to describe all variables. Results: The total number of calls were 5137, 5508, and 5181 in 2018, 2019, 2020, respectively. The monthly call number during 2020 was mostly less than in 2019. More calls were received from the public calls (39.4% vs 33.1%) and for accidental exposures (65.6% vs 62.3%) increased during 2020 compared to 2019. Exposures to pharmaceuticals decreased by 14.8% from 2019 to 2020, while exposures to eucalyptus oil more than doubled from 21 in 2019 to 43 during 2020. Exposures to antiseptics and disinfectants increased by 60.4%, mainly due to hand sanitizers exposure which showed a 26-fold increase from 2019 (n = 6) to 2020 (n = 156). Conclusion: A change in the profile of poison exposures was observed during the COVID-19 pandemic. Lockdown regulations and greater availability of antiseptics and disinfectants probably led to the increase in exposures. Although symptoms were mostly mild, the public should be educated on safe storage and proper use of all chemicals.

The burden of intentional self-poisoning on a district-level public Hospital in Cape Town, South Africa

Introduction:Intentional self-poisoning is a significant part of the toxicological burden experienced by emergency centres. The aim of this study was to describe all adults presenting with intentional self-poisoning over a six-month period to the resuscitation unit of Khayelitsha Hospital, Cape Town.Methods:Adult patients with a diagnosis of intentional self-poisoning between 1 November 2014 and 30 April 2015 were retrospectively analysed after eligible patients were obtained from the Khayelitsha Hospital Emergency Centre database. Missing data and variables not initially captured in the database were retrospectively collected by means of a chart review. Summary statistics were used to describe all variables.Results:A total of 192 patients were included in the analysis. The mean age was 27.3 years with the majority being female (n = 132, 68.8%). HIV-infection was a comorbidity in 39 (20.3%) patients, while 13 (6.8%) previously attempted suicide. Presentations per day of the week were almost equally distributed while most patients presented after conventional office hours (n = 152, 79.2%), were transported from home (n = 124, 64.6%) and arrived by ambulance (n = 126, 65.6%). Patients spend a median time of 3h37m in the resuscitation unit (interquartile range 1 h 45 m­7 h 00 m; maximum 65 h 49 m). Patient acuity on admission was mostly low according to both the Triage Early Warning Score (non-urgent n = 100, 52.1%) and the Poison Severity Score (minor severity n = 107, 55.7%). Pharmaceuticals were the most common type of toxin ingested (261/343, 76.1%), with paracetamol the most frequently ingested toxin (n = 48, 25.0%). Eleven patients (5.7%) were intubated, 27 (14.1%) received N-acetylcysteine, and 18 (9.4%) received benzodiazepines. Fourteen (7.3%) patients were transferred to a higher level of care and four deaths (2%) were reported.Discussion:Intentional self-poisoning patients place a significant burden on emergency centres. The high percentage of low-grade acuity patients managed in a high-acuity area is of concern and should be investigated further

A 3-year Survey of Acute Poisoning Exposures in Infants Reported in Telephone Calls made to the Tygerberg Poison Information Centre; South Africa

Background. Infants undergo rapid development changes and are particularly vulnerable to toxic chemicals. Identifying and evaluating the toxic risks that exist in this age group could be very valuable when making recommendations on how to prevent specific types of poisoning.Objectives. This study analysed the toxic substances responsible for acute poisoning exposures in infants (1 year of age) as well as the severity of the exposures.Methods. A retrospective analysis of the Tygerberg Poison Information Centre (TPIC) database was conducted over a 3-year period (1 January 2011 to 31 December 2013). Descriptive statistics are provided for the entire study population as well as for the neonatal subgroup (30 days old).Results. The TPIC handled 17 434 consultations during the 3-year study period. Infants were involved in 1 101 cases (6.3%); of which 46 cases (4.2%) were neonates. Most enquiries about infants were associated with non-drug chemicals (n
